“…Reducing the dose of nano-chitosan-urea application to 1000 mg N L -1 resulted also in significant increases in the outcome yield quantity and quality and these results were comparable with those obtained from the full application dose of urea. Probably, the large surface area and small size of chitosan (Djiwanti and Kaushik, 2019) accounts for increasing the N-utilization when used as carriers for N fertilizers (Kalia and Kaur, 2019). Its worthy to mention that inoculating plants with AMF was not efficient enough for improving the plant growth when associated with the highest application rate (1500 mg N L -1 ) of nano-chitosan-urea.…”

The current research aims at producing high kohlrabi knob yield with better quality traits using nanochitosan-urea (versus urea) as a foliar spray in presence of mycorrhiza (AMF) as plant inoculants either solely or in combinations with each other. This investigation was carried out under the field conditions for two successive seasons (2015/2016 and 2016/2017). In this concern, microrrhizal inoculations were set up in the main plots whereas the foliar application of nano-urea was arranged in the sub-plots, comprising 5 treatments, i.e. spray with water, spray with ordinary urea at a rate of 1500 mg N L-1 , spray with nano-urea at rates of 500 mg N L-1 , 1000 mg N L-1 , and 1500 mg N L-1 (designated U0, U1, U2, U3, and U4 respectively). Generally, spraying kohlrabi plants with different urea forms increased significantly the studied vegetative growth parameters as well as the yield quantity and quality traits in the following order U4>U1=U3>U2>U0. Likewise inoculating plants with AMF improved significantly the investigated growth parameters and yield components. It seems that inoculating plants with AMF did not affect significantly the above-mentioned growth parameters and yield components when plants sprayed with nano-chitosan-urea at a rate of 1500 mg N L-1. Thus, spraying plants with 1000 mg N L-1 as nano chitosan-urea together with plant inoculation with AMF (U3M1) is the recommended solution to cut off the inputs of chemical N fertilizers by 33.3% as this integrated treatments recorded comparable results with the ones attained for the application of the full dose of urea.

“…Nano-fertilizers can improve the yield and quality of crops with increased nutrient usage efficiency, while lessening the production cost and thereby resulting in a sustainable agriculture [34][35][36][37][38]. The use of pesticide is a common practice in agriculture and several studies have been carried out for the advancement of effective pesticides [39][40][41][42]. Considering the environment sustainability, bio-based pesticides are being developed to reduce the dangerous impacts of artificial pesticides.…”

Nanotechnology implies the scientific research, development, and manufacture, along with processing, of materials and structures on a nano scale. Presently, the contamination of metalloids and metals in the soil has gained substantial attention. The consolidation of nanomaterials and plants in ecological management has received considerable research attention because certain nanomaterials could enhance plant seed germination and entire plant growth. Conversely, when the nanomaterial concentration is not properly controlled, toxicity will definitely develop. This paper discusses the role of nanomaterials as: (1) nano-pesticides (for improving the plant resistance against the biotic stress); and (2) nano-fertilizers (for promoting the plant growth by providing vital nutrients). This review analyzes the potential usages of nanomaterials in agroecosystem. In addition, the adverse effects of nanomaterials on soil organisms are discussed. We mostly examine the beneficial effects of nanomaterials such as nano-zerovalent iron, iron oxide, titanium dioxide, nano-hydroxyapatite, carbon nanotubes, and silver- and copper-based nanomaterials. Some nanomaterials can affect the growth, survival, and reproduction of soil organisms. A change from testing/using nanomaterials in plants for developing nanomaterials depending on agricultural requirements would be an important phase in the utilization of nanomaterials in sustainable agriculture. Conversely, the transport as well as ecological toxicity of nanomaterials should be seriously examined for guaranteeing its benign usage in agriculture.

“…The reduction in toxicity of mancozeb-loaded nanoformulation may be due to the slow and sustained release of mancozeb from the CSGA nanomatrix [ 40 , 64 , 65 ]. Similarly, the encapsulated herbicide paraquat was found to be less toxic to alveolar and mouth cell lines (A549), as compared against the trade form.…”

Biopolymers such as chitosan and gum acacia are used for nanotechnological applications due to their biosafety and ecofriendly nature. The commercial fungicide mancozeb (M) was loaded into chitosan–gum acacia (CSGA) polymers to form nanocomposite (NC) CSGA-M (mancozeb-loaded) measuring 363.6 nm via the ionic gelation and polyelectrolyte complexation method. The physico-chemical study of nano CSGA-M was accomplished using dynamic light scattering (DLS), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). Nano CSGA-M-1.0 (containing 1.0 mg/mL mancozeb) at 1.5 ppm demonstrated a maximum inhibition (83.8 ± 0.7%) against Alternaria solani, while Sclerotinia sclerotiorum exhibited a 100% inhibition at 1.0 and 1.5 ppm through the mycelium inhibition method. Commercial mancozeb showed an inhibition of 84.6 ± 0% and 100%, respectively, for both fungi. In pot house conditions, NCs were found to exhibit good antimicrobial activity. Disease control efficiency (DCE, in %) in pathogen-treated plants for CSGA-M-1.0 was 64.6 ± 5.0 and 60.2 ± 1.4% against early blight and stem rot diseases, respectively. NCs showed lower cytotoxicity than commercial mancozeb at the given concentration. In conclusion, both in vitro and in vivo antifungal efficacy for nano CSGA-M was found to be quite comparable but less toxic than mancozeb to Vero cell lines; thus, in the future, this formulation may be used for sustainable agriculture.
